In situ X-ray diffraction (XRD) method was used to investigate the Co3O4 reduction in catalyst supported on γ-Al2O3 and oxide monophase sample. Initial structure of Co3O4 in both samples is similar and contains vacancies in the cation positions. In spite of this reduction process of Co3O4 is different for supported and monophase samples as has been shown by in situ XRD. In monophase sample the cobalt oxide is reduced to metallic cobalt (hcp) directly. On the contrary the two-stage reduction is observed for supported sample: Co3O4 is reduced to CoO and then to metallic Co (fcc). In both cases nanoparticles of metallic cobalt contains high concentration of stacking faults.
